Black Diamond's newest addition to their Camalot family, the X4 combines the holding power of a four-cam unit with a narrower profile to really get into those tight spots other cams just won't. Similar to the C4, this cam has a double axle (.75, .5, and .4 sizes) or stacked axle (.3, .2 and .1 sizes) for more expansion range per size than any small four-cam unit on the market. In fact, the six sizes of the Camalot X4 cover the same range as eight sizes of comparable units. The embedded cam springs allow for an ultra-narrow head width. The X4 has a segmented casing protecting the cable stem, made with super-durable aluminum protection beads, so it can withstand repeated abrasion without losing any flexibility. Featuring a hot-forged trigger bar, and a symmetric swage which improve handling and eliminate buckling. Plus, lightweight dyneema sling is color coded and can be paired with Oz, Hoodwire, and Neutrino rackpacks (available separately) for quick reference on the go. Make room in your trad rack for the newest gold-standard camalot from Black Diamond.
When you're trying to climb your way up that vertical rock wall, you'll want to be sure you have the best available tools at your disposal.

Black Diamond Camalot X4 Cam Reviews:


X4 Camalot

Everybody is familiar with Black Diamond's superior expansion range in their C4s, so it's good to see that same benefit brought to the finger-sized X4s. More range equals less nervous fiddling during those in-between finger sized cracks and hard-to-read placments.

The heads on the X4 are almost exactly one lobe narrower than the C4s. I've used the X4s on familiar climbs where some C4 placements were always a bit questionable--a lobe or 2 not quite biting into the rock because of wavy places in the crack. The narrower headwidth of the X4s eliminates this issue by allowing all 4 lobes to bite into only the most uniform features of lumpy cracks. The X4 is perfect for basalt fissures.

My only issue with the X4 is that the stem is significantly more limp than any other cam I've used. When you pull the trigger, the head flops to the side, somewhat bending the entire unit. It's strange to place a floppy cam and can make some placements feel tricky, like you've got a garden hose in your hand when you want a pipe. I'm sure it'll just take some getting used to, and I could see how the softer stem could absorb some rope wiggle and prevent some walking. Still, for now, it's kind of weird.

Ultra-flexible stems are NOT a CON. Flexible stems mean that the cam will be less likely to walk in its placement, and that it will stay in a horizontal placement well when loaded or fallen on. Ever climbed on Aliens?
The head on these things is about 25% more narrow than their C4 predecessors which is awesome. That is also NOT a CON. The only gripe I have about these is the "symmetrical swage" design. In an effort to make a more aesthetic piece, BD actually created a point for the cable to bend rather easily. The "cap" that covers the swage point causes the cable to bend slightly after they've been used a few times. It's NBD, but still. The shining pros of this cam are the head width, double and stacked axle design which gives them better range, and INCREASED FLEXIBILITY. The beaded stem is nice and is chiefly what makes them better than their closest competitor. The price point I'm not crazy about, but whatever. These are sweet cams to be sure, but I'm not quite ready to go out and pay that price to augment what I already have in that range from another brand. If you're looking to build a rack on the small end, these would be an excellent choice.

Brilliant little cam!

The X4 excels at shallow, horizontal, narrow pin scar and thin crack placements thanks to its narrow head and flexible stem design. The first thing you'll notice about the X4s is the elegant appearance and smooth camming action. Like the C4, the spring tension feels consistent through the entire cam stroke. The X4 has the overall look and feel of a quality product. What sets the X4s apart from other single stem micro cams is the expanded placement range thanks to double and stacked axles. The larger sizes, .4, .5 & .75 are equipped with double axles just like a Camalot C4. The smaller sizes have "stacked axles" that give them an expanded range to a proportionately lesser extent. The X4 is loaded with trick details. The cams springs are embedded in the cam lobes allowing the 4 lobe head to remain narrow and lending the X4 a clean appearance. The single cable stem is armored to protect it from fraying and joins the thumb loop at a symmetrical swage. The X4 is slung with light but strong Dyneema and the colors correspond with C4s from .3 to .75 so climbers accustomed to using C4s will have no problem grabbing the correct size.

.1 used at Tallulah Gorge

Purchased a .1 X4 in lieu of a black alien. As a fan of aliens, I was skeptical, but the .1 performed flawlessly and was easy to set on a recent route at Tallulah Gorge. So far the product seems great, but really need to use a few more times to really see how it performs in other situations. I do like the fact that the springs are located internally in the lobes and that there are no collars on each end of the outer lobes.

Master Cam meet C4

A very cool piece of gear, that was previously missing from the BD lineup. It is as though a C4 and a master-cam had a baby. The only downfall is that the stem is so flexible that when reaching for a high placement the head flexes a bit and may not slide down into a placement from above as desired. But that is a tradeoff as the piece inspires great confidence in horizontals and non-desperate placements.

This is a great lightweight cam, the narrow head is great for getting in anywhere.
